ANDREW J. GUNTER, OF NORWOOD, OHIO.

WBELLOWS.

SPECIFICATION forming part of Letters Patent No. 321,367, dated February24, 1903.

Application filed May 26,1962. Serial No. 109,101. (No model.)

To all whom it may concern:

Be it known that I, ANDREW J. GUNTER, a citizen of the United States,and a resident of Norwood, in the county of Hamilton and State of Ohio,have invented a certain new and useful Improvement in Bellows, of whichthe following is a full, clear, and exact description, reference beingbad to the accompanying drawings, which form a part of this specifica-IO tion.

yet simple in construction, having more especially to do with the methodof connecting the leaves or bellows-plates to the spout, as will be morefully hereinafter described.

In the drawings, Figure 1 is a sectional View of the forward or spoutend of a bellows constructed in my improved manner, taken on the line XX of Fig. 2. Fig. 2 is a plan view of the bellows with the upper leaf orplate removed to show the method of attachment of the spout to the lowerleaf and in order to more clearly illustrate the construction of thebellows.

Like letters of reference indicate identical parts in the differentfigures.

A A are the bellows-plates or leaves, which are generally constructed ofwood, with their forward or spout end made tapering in'the usual mannerand provided with the rearwardly-extending handle portion a when ofbellows are operated. I

B is the spout, constructed of metal an given the desired taperingshape, as clearly illustrated in Fig. 2. This spout must of 3 5 thehand-bellows type, by means of which the 0 course be retained in place,and to this end I prefer to secure the same to one of the bellows-platesor leaves-t0 wit, A. I find in constructing the bellows that it isdesirable to give the spout B a flattened oblong shape,

5 as shown in Fig. 2, at its inner end, thus enabling me to makeair-tight connnections at this point.

Secured in any suitable manner or made integral with the leaf A, towhich the spout B is attached, are head-blocks b b, which are adapted tofit snugly against the sides of the spout B to prevent the passage ofair at the sides of the spout. These blocks 1) also furnish anattaching-surface for the leather 0, which is used to produce anair-tight joint between the hinge d and the spout B, as well as alsoclosing the joint between the upper leaf A and the spout B at the point6, without which it would not be possible to make an airtightconstruction.

By constructing a bellows in my improved manner I am enabled to securethe spout to the leaf of the bellows and one plate of the hinge togetherby one and the same rivets ff.

It will be seen that my improved bellows is very simple in constructionand inexpensive to manufacture, and I am enabled also to produce abellows which will be very efficient and air-tight. It will be also seenthat the blocks 1) b furnish a surface for securing the portion of thebellows-leather thereto, or a strip of leather may be secured about thespout on the outer sides of the plates and blocks 19, beneath which theends of the bellows-leather may be placed and then securely fastened.

By constructing a bellows as herein described, and illustrated in thedrawings accompanying this specification, it is not necessary to gougeout the bellows-plates on the inside near the inner end of the spout toform a passage forthe air, as the entire inner orifice of the spout Blies between the bellowsplates.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a bellows, the combination with the bellows plates, a metallicspout, of headblocks adapted to conform to the contour of the metallicspout, a strip of leather secured to said head-block across the spoutand to one of the bellows-plates and a hinge secured to the spout andone of the bellows-plates, substantially as shown and described;

2. In a bellows, the combination of the bellows-plates, a metallicspout, one of said bellows-plates provided'with head-blocks adapted toreceive the spout, a strip of leather passing across the spout andsecured to the headblocks', and a hinge whose one leaf is fastened onsaid spout byrivets securing the spouthinge and head-block platetogether, substantially as and for the purpose described.

3. In a bellows, the combination with belend of the other bellows-plate,the hinge and lows-plates, an enlarged end on one of said spout andenlarged end plate being secured 10 plates conforming to and adapted toreceive together by rivets substantially in the manthe spout, a hingefor securing the two plates ner described.

5 of the bellows together, and a washer of suit- ANDREW J. GUNTER.

able material placed between the one leaf of Witnesses: the hinge andthe spout and secured to the GEORGE HEIDMAN, enlarged end of said plateand to the outer l EDWARD HAAT.
